  • Visible light band reflection metasurface device and reflected light wavelength modulation method
    Patent number: 11092870
    Abstract: A visible light band reflection metasurface device and a reflected light wavelength modulation method. The device successively includes, from top to bottom, a metal metasurface layer with periodically arranged antenna units, a modulation layer formed by an electro-optic material, a metal reflection layer and a substrate layer; the antenna unit period is less than the incident wavelength, and the thickness is greater than the skin depth of metal and less than 100 nm; the thickness of the modulation layer is less than the wavelength of the incident light; and the thickness of the metal reflection layer is greater than the skin depth of metal and less than the wavelength of the incident light; and an external voltage source can modulate the color of the reflected light, and can achieve voltage modulation of the color of reflected light in the visible light band.
